NEW YORK- Senior Mallory Burdette extended her stay at the 2012 U.S. Open, defeating Switzerland's Timea Bacsinsky 6-4, 6-3 on Monday night in the opening round of main draw singles play.

A wildcard in the main draw, Burdette next plays Lucie Hradecka of the Czech Republic in the second round.

Burdette has enjoyed a successful summer testing her game on the pro circuit, collecting singles crowns at the Hospital Tennis Classic ($10,000 USTA Pro Circuit) and Odlum Brown Vancouver Open ($200,000 USTA Pro Circuit), which earned her a main draw U.S. Open wildcard. Back in July, Burdette picked up her first career WTA victory in the Bank of the West Classic opening round before hanging tough early on against 10th-ranked Marion Bartoli in a 7-5, 6-0 loss.

A two-time NCAA doubles champion, Burdette teamed with Nicole Gibbs to win this year's title one season after bringing home the 2011 crown with Hilary Barte. The 2012 NCAA singles runner-up, Burdette has compiled a 104-22 overall singles record in three seasons.

Gibbs was not as fortunate, dropping a 7-5, 6-3 decision to France's Alize Cornet. Gibbs' stock continues to rise, bringing home the hardware at the Colorado International ($50,000 ITF Pro Circuit) in July before a recent strong showing at the New Haven Open in which she won three qualifying matches and her main draw opener.

A three-time All-American, Gibbs is coming off one of the best seasons in school history, becoming only the third player in NCAA history to capture both the NCAA singles and doubles titles in the same season. Stanford's first NCAA singles champion since Amber Liu in 2004, Gibbs was also named the 2012 Honda Sports Award recipient and ITA National Player of the Year. In just two seasons, Gibbs has produced an 87-11 overall record and 48-2 mark in dual match play.

Gibbs still has tennis to play however, as she and Burdette will square off against the sister duo of Serena Williams and Venus Williams in the opening round. Burdette and Gibbs captured the 2012 NCAA doubles crown, collecting Stanford's 15th overall collegiate doubles titles in school history and eighth since the NCAA adopted its current format in 1982. Burdette and Gibbs wrapped up the year 35-5 overall, 18-2 in duals, 17-3 in tournament play and 18-4 against nationally-ranked opponents.
